Abstract

Apparatus for the industrial processing of a material by a fiber laser, which fiber laser emits optical radiation, the apparatus configured such that the optical radiation forms an optical power distribution on a surface of the material, including first and second optical powers which are located at respective first and second radii from a center of the optical power distribution and which are of substantially higher intensity than a third optical power which is located at a third radius from the center of the optical power distribution and which is smaller than the first and the second radii.
